hi

 

ive got a pair of Girling calipers that came with the hillclimb mini, but we swapped them out for standard cooper S calipers (needed new calipers in a hurry)

 

the calipers are massive (nearly 50mm diamiter pistons) but are incredibly light , they have been modified to fit under 10 inch wheels (someone took a grinding wheel to them, (photos attached))

 

i recon they would be worth fixing before next season as they should be an inprovement on the standard cooper ones, but does anyone know how they might compare to 4-Pot calipers?

I would hazard a guess that the previous owner installed them to reduce the unsprung weight. The fluid movement required to push the pistons may change the travel of the pedal, but then this depends on the rest of the system (mc and rwc). They look old so maybe a light alternative to the current in favour 4 pots..

I would doubt they will improve the braking persay, but they may feel different.

But then I have never run them spits all IMO.

These cailpers are 4lbs lighter than a std S caliper. work well, but will not fit under S steel wheels and some alloys.

any idia what type of caliper they might be?

 

i am hoping to get some off the shelf pads rather than getting some made up but i have no idia what model of caliper these are. i guess girling dont make these any more

They should take standard 7.5 inch S pads, if i remember correctly they were used on the rear of some F3 cars

Girling racing caliper from the 60s, but still produced after that. Use Lotus Elan front pads from 62/73, so there is no problem finding pads. Std S pads do not fit.

good news, found out that the calipers are Girling AR (2 inch pistons) that were used on a number of historic race cars, thanks to everyone particuarly Ivor for putting me down the right path. no sortage of pad options now
